<p>PURPOSE:To transmit the oscillation of an oscillation generating part to an oscillation transmitting plate at a proper angle independently of an operation angle by pivoting the end part of an oscillation pen around the body part of the pen. CONSTITUTION:The oscillation generating part constituted of an oscillator 4 and a horn part 5 is fixed in a ball-like holding member 25 and only the horn part 5 is exposed to the tip part of the oscillation pen 3. The holding member 25 is engaged with a mount part 28 having an inner diameter almost equal to the outer diameter of the holding member 25 on the tip part of a case 21 and the member 25 can be optionally rotated in a required direction. The mount part 28 is worked like a split shape and is capable of fixing the holding member 25 by moving a ring-like chuck 29 to the pen tip side. Thereby, the horn part 5 can be optionally adjusted in accordance with a grip angle obtained when an operator operates the oscillation pen 3.</p> |
